Certified Radon Mitigators
in Centennial, Colorado

Centennial in southern Arapahoe County is one of the Denver metro's newest incorporated cities, but its radon risk is the same as the older communities it surrounds. Douglas and Arapahoe county geology — glacial till over Cretaceous sedimentary rock near the Front Range — produces radon across Centennial's planned communities including Willow Creek, Foxridge, and Piney Creek. Colorado's EPA Zone 1 designation covers most of the south suburban area, and Centennial's newer construction doesn't reduce risk — modern tight-construction homes often accumulate more radon than drafty older homes. Mitigation systems are routinely installed in both new and existing Centennial homes.
